The casting machine 100 provided in this embodiment includes at least one station for installing the mold 500, the station includes an upper mold base 120 and a lower mold base 130, the upper mold base 120 is used for installing the upper mold 510 of the mold 500, and the lower mold base 120 is used for installing the upper mold 510 of the mold 500. The mold base 130 is used to install the lower mold 520 of the mold 500, and the station further includes a first driving member, and the first driving member is used to drive the upper mold base 120 and the lower mold base 130 to move relative to the mold opening position and the mold clamping position. Switch between, in the mold opening position, the upper mold 510 and the lower mold 520 are attached, and are in a pourable state, in the mold opening position, the upper mold 510 and the lower mold 520 are separated.

In practice, for the convenience of control and arrangement of related components, the relative movement direction of the upper die base 120 and the lower die base 130 is parallel to the vertical direction.

As above, the casting machine 100 can be used for casting production. During production, the mold 500 can be closed or opened by controlling the relative action of the lower mold base 130 and the upper mold base 120 by the first driving member. 500's automatic operation of mold opening and mold closing, compared with the traditional way of relying on manual mold opening and mold closing, greatly reduces the labor intensity of labor, reduces human factors, and can improve the efficiency of casting production and reduce labor costs. At the same time, it can improve the consistency of casting production quality.

In addition, the casting machine 100 also provides conditions for full automation of casting production. For example, in practical applications, multiple casting machines 100 can be arranged in the same direction to form a pouring line, and the automatic pouring machine can be used to move along the track to the casting machine. The mold 500 in the mold clamping position at each station of the 100 performs the liquid injection operation.

1 In the orientation shown in FIG. 2 , the front refers to the side close to the left side, and correspondingly, the rear refers to the side close to the right side.

During the specific setting, the adjacent front support columns 112 are arranged at a certain distance, the number of the front support columns 112 and the rear support columns 113 are the same, and the positions are in a one-to-one correspondence. A work station is formed between the support columns 113 .

Each station is correspondingly provided with an upper mold base 120 and a lower mold base 130. The upper mold base 120 is used to install the upper mold 510 of the mold 500, and the lower mold base 130 is used to install the lower mold 520 of the mold 500. The 130 can move vertically relative to the upper die holder 120 to switch between the die opening position and the die closing position.

For a casting machine 100, more than two stations can be set on the frame 110, and the stations can be arranged in a straight line, so that the pouring stations in the subsequent formation of the pouring line are all on a straight line, which is convenient for Control the movement of the pouring machine and the liquid injection operation; at the same time, it can also improve the compactness of the structure.

It can be understood that, in practical application, the casting machine 100 does not have to form a pouring line, and a single casting machine 100 can also be used in conjunction with an automatic pouring machine.

In the solution shown in the figure, there are four corresponding support columns at the front and the rear of the casting machine 100 respectively, so that one casting machine 100 has three stations.

In practical application, the number of stations of the casting machine 100 is set as required.

In this embodiment, in order to reduce the driving structure, the position of the upper mold base 120 is relatively fixed, and the lower mold base 130 can move vertically toward or away from the upper mold base 120 . In actual setting, if there is no other requirement, of course, the lower mold base 130 can also be relatively fixed, and the upper mold base 120 can move vertically toward or away from the lower mold base 130 .

Specifically, the upper die base 120 is fixed to the upper end of the frame 110 relative to the base 111 , and can be fixedly connected to the front support column 112 and the rear support column 113 at corresponding positions.

It should be pointed out that the structure of the upper mold base 120 should be such that the upper surface of the upper mold 510 is exposed after being installed, so that after assembly, the gate of the mold 500 is exposed to facilitate subsequent liquid injection operations.

In this embodiment, since the upper mold base 120 and the frame 110 are relatively fixed, in actual setting, the upper mold base 120 corresponding to each station can be formed into an integral structure, for example, an integrated upper mold base is provided, and the upper mold base has The upper die holder 120 corresponding to the number of stations.

In this embodiment, the lower mold frame 130 can move vertically. In order to make the actions of each station relatively independent, the lower mold frame 130 corresponding to each station is set independently.

In this embodiment, the lower mold base 130 includes a lower mold base 132 and a lower turning base 133, the lower turning base 133 is used to install the lower mold 520, the lower turning base 133 is rotatably connected to the lower mold base 132, and also includes a second driving member, The second driving member is used to drive the lower inversion seat 133 to rotate relative to the lower mold seat 132 to drive the lower mold 520 to turn over to the blanking position. When the lower mold 520 is at the blanking position, the casting formed in the lower mold 520 can fall under the action of gravity.

Specifically, on the basis of setting a plurality of stations, the rotation center line of the lower inversion seat 133 relative to the lower die seat 132 is parallel to the arrangement direction of the plurality of stations.

Specifically, the lower turning base 133 can be rotatably connected with the lower die base 132 through the rotating shaft 1331 .

In this way, the automation degree of the casting machine 100 can be further improved, and after the casting is completed, there is no need to manually take out the casting. It also provides conditions for full automation of casting. For example, in practical applications, when forming the aforementioned pouring line, a horizontal conveying mechanism parallel to the pouring line can be provided, and the horizontal conveying mechanism is located below the casting machine 100 on the pouring line. The castings dropped by the casting machine 100 are convenient to uniformly transport the castings to a designated place.

On this basis, in order to enable the casting formed by the casting machine 100 to smoothly drop to a desired position, the casting machine 100 further includes a blanking part 170 located under the lower mold frame 130 .

Specifically, the blanking part 170 is inclined downward, and its upper receiving end 170a is located below the lower die base 132. Obviously, the receiving end 170a of the blanking part 170 refers to the end close to the lower die 520, and the discharging end 170b refers to the end relatively far away from the material receiving end 170a, and the casting is separated from the blanking member 170 after being guided by the blanking member 170.

In actual setting, the discharge end 170b of the blanking part 170 can be connected with other containers for storing castings according to needs, in addition to the aforementioned horizontal conveying mechanism.

As shown in the figure, the blanking member 170 specifically includes a bottom wall portion 171 and side wall portions 172 fixed on both sides of the bottom wall portion 171. The wall portion 172 can prevent the falling casting from coming off the blanking member 170 .

In the illustrated scheme, the upper end of the blanking part 170 is located in front of the front support column 112 to ensure that the casting can enter the blanking part 170 when it falls, and the whole is inclined backward and downward relative to the frame 110, so that the casting can rely on gravity to move along the blanking part. The inclined direction of 170 automatically falls, so that the pouring end is relatively located on the front side of the frame 110, and the discharge end of the formed casting is relatively located on the rear side of the frame 110, and the two do not interfere with each other, which is convenient for the automatic pouring machine mentioned above. The horizontal conveying mechanism together forms the casting line.

Specifically, the material receiving end 170a of the blanking member 170 is further provided with a baffle plate 173 fixedly connected with the bottom wall portion 171 and the side wall portions 172 on both sides. The falling part 170 is disengaged, so that it can be inclined and dropped to the discharge end 170b along the bottom wall part 171 .

Specifically, the bottom wall portion 171 of the blanking member 170 includes a first inclined section 1711 relatively close to the material receiving end 170a and a second inclined section 1712 relatively far away from the material receiving end 170a. The angle between the first inclined section 1711 and the horizontal plane is greater than The angle between the second inclined section 1712 and the horizontal plane. In this way, the inclination of the part of the blanking part 170 close to the discharge end 170b thereof is set to be relatively small, so as to provide a buffer for the casting, so that the blank can be smoothly blanked.

In this embodiment, the lower mold base 132 of the lower mold frame 130 is specifically slidably connected to the rear support column 113 of the frame 110 to slide vertically under the driving of the first driving member.

Specifically, a sliding block 131 is fixed on the lower die base 132 , a guide rail 1131 extending vertically is installed on the rear support column 113 , the lower die base 132 is slidably matched with the guide rail 1131 through the sliding block 131 , and the sliding block 131 and the guide rail 1131 The matching can provide guidance for the vertical movement of the lower mold base 132, and ensure the directionality of the lower mold base 132 to drive the lower mold 520 to move.

In actual setting, the lower die base 132 and the front support column 112 may also be provided with sliding blocks and guide rails that cooperate with each other, specifically so that the lower die base 132 can move vertically and stably.

In this embodiment, the first driving member is specifically a mold clamping oil cylinder 140 , which drives the lower mold base 132 to move vertically upward or downward through the expansion and contraction of the mold clamping oil cylinder 140 .

Specifically, the cylinder body of the clamping cylinder 140 is fixedly connected to the base 111 of the frame 110, and the telescopic rod is fixedly connected to the lower mold base 132. When the telescopic rod of the clamping cylinder 140 is extended, it drives the lower mold base 132 to move up vertically, and the closing When the telescopic rod of the mold cylinder 140 is retracted, the lower mold base 132 is moved vertically downward.

In this embodiment, a limit switch can be provided on the upper mold base 120. When the mold clamping oil cylinder 140 drives the lower mold base 132 to move to the position where the lower mold 520 and the upper mold 510 are clamped, the limit switch can feed back a command to the casting The casting control unit of the machine 100 is used to stop the operation of the mold clamping oil cylinder 140, so as to avoid the movement transition and cause the collision loss of the relevant components.

In this embodiment, the second driving member is specifically an overturning oil cylinder 150, the fixed end of the overturning oil cylinder 150 is hinged with the lower mold frame 130, the telescopic end is hinged with the lower overturning seat 133, and the lower overturning seat 133 is driven by the telescopic end of the overturning oil cylinder 150. Flip around its axis of rotation 1331.

In the illustrated scheme, the fixed end of the overturning oil cylinder 150 is specifically hinged with the lower end of the mounting seat 134 (described below) of the lower die frame 130, and the telescopic end is hinged with the lower end of the lower overturning seat 133, and is configured as: the telescopic end of the overturning oil cylinder 150 When extending, the lower mold 520 installed on the lower flip seat 133 is in a state capable of being mold-clamped with the upper mold 510. When the telescopic end of the flip cylinder 150 is retracted, the lower flip seat 133 is driven to rotate downward in the direction of the front support column 132. , to drive the lower mold 520 to turn over to a blanking position capable of blanking, that is, a position where the opening of the lower mold cavity of the lower mold 520 faces downward. In practice, the specific arrangement form of the overturning oil cylinder 150 can also be other.

In this embodiment, the frame 110 of the casting machine 100 is also provided with relevant hydraulic pipelines connected to the mold clamping cylinder 140 and the overturning cylinder 150 and a hydraulic valve group for controlling the actions of each cylinder. As shown in FIG. The top of the rear side of the 110 (that is, the side where the rear support column 113 is located) is fixedly connected to the mounting plate 114 for installing these pipelines and hydraulic valve groups. Similarly, the mounting plate 114 can also install some cooling media related to the cooling system at the same time. The pipeline 180 makes the structure more compact.

Here, the cooling system refers to a system for cooling the casting after pouring. Specifically, a cooling channel is provided inside the mold 500, and the cooling medium source of the cooling system can be communicated with the cooling channel of the mold 500 through a cooling pipeline, so that cooling The medium flows through the cavity to cool the casting.

In another embodiment, a detection switch 190 may be installed on the upper mold base 120. After casting is completed, after the lower mold base 130 drives the lower mold 520 to move to the mold-opening position, the detection switch 190 can detect that the upper mold 510 has retained castings. When the hold signal is sent to the casting control unit, the casting control unit sends an alarm signal. In practical applications, after the mold is opened, the upper mold 510 and the lower mold 520 are separated, but the casting may stay on the upper mold 510, which not only affects the subsequent blanking and the next cycle of pouring, but also poses a safety hazard. The setting of the detection switch 190 This problem can be avoided. When it is detected that a casting is stuck in the upper mold 510, a feedback signal can be sent to the casting control unit, so that the casting control unit can send an alarm signal to remind the operator to deal with it in time.

It can be understood that the hydraulic valve group controlling the action of each oil cylinder and the aforementioned limit switch and detection switch 190 can be connected in communication with the casting control unit of the casting machine 100 to perform corresponding actions according to the received instructions.

In practical applications, the first driving member and the second driving member may not be in the form of oil cylinders, for example, cylinders or other driving members may be used.

In this embodiment, the casting machine 100 is further provided with a smoke spraying mechanism 160, so as to spray carbon deposits on the surface of the cavity of the mold 500 to form a carbon deposit layer before one casting, so as to facilitate demolding.

The smoke spraying mechanism 160 can also be automatically controlled to avoid manual painting of an isolation protective layer on the surface of the cavity of the mold 500 that facilitates demolding.

In this embodiment, the smoke spraying mechanism 160 is specifically installed on the lower mold base 130 , and can move together with the lower mold base 130 so as to be adjusted in a proper position, and can align the lower mold 520 on the lower mold base 130 and the upper mold base 120 The upper mold 510 of the upper mold 510 simultaneously performs the operation of injecting carbon deposits.

Of course, in the actual setting, the positions of the smoke spray mechanism 160 and the frame 110 can also be relatively fixed, so that the mold clamping cylinder 140 needs to drive the lower mold 520 to move to a suitable position, so that the smoke spray mechanism 160 can simultaneously face the upper mold 510 and the lower mold 520. Do your homework.

Specifically, the lower mold frame 130 further includes a mounting seat 134 fixed to the lower mold base 132 , the mounting seat 134 is mainly located on the rear side of the rear support column 113 , and the smoke spraying mechanism 160 is installed on the mounting seat 134 to prevent spraying During the carbon deposition operation, the operation of other components of the casting machine 100 is not affected.

In this embodiment, the smoke spraying mechanism 160 includes a driving component 161 , a mounting platform 162 , an air ring 163 and an ignition needle 164 .

The gas ring 163 and the ignition needle 164 are mounted on the mounting table 162. The gas ring 163 has an air inlet 1631 for the combustion medium to flow in. The gas ring 163 is provided with a plurality of air holes 1632 along its circumference.

The driving component 161 is used to drive the mounting table 162 to move to switch the air ring 163 between the firing position between the upper mold 510 and the lower mold 520 and the non-firing position exiting between the upper mold 510 and the lower mold 520 .

The ignition needle 164 can ignite the combustion medium at each air hole 1632 to form a carbon deposit layer in each upper mold cavity of the upper mold 510 and each lower mold cavity of the lower mold 520 to facilitate subsequent demoulding. Obviously, the ignition operation of the ignition needle 164 is performed when the gas ring 163 is in the ignition position between the upper mold 510 and the lower mold 520 .

For the convenience of arrangement, as shown in FIG. 4 and FIG. 5 , each air hole 1632 of the air ring 163 is opened on its upward facing surface, and the ignition needle 164 is specifically located above the air ring 163, in order to ignite the combustion medium at each air hole 1632 at the same time. , the ignition needle 164 is preferably located in the middle area of the gas ring 163 .

During the specific installation, the mounting table 162 is installed on the mounting seat 134 of the lower mold frame 130 through the support frame 165, and the mounting table 162 is slidably connected with the support frame 165. The sliding direction of the mounting table 162 can be set to be parallel to the front-rear direction of the frame 110, That is, the mounting table 162 can move to the front side of the frame 110 relative to the support frame 165 to drive the air ring 163 and the ignition needle 164 thereon to move together between the upper mold 510 and the lower mold 520 , or to the frame 110 relative to the support frame 165 . The rear side moves to exit between the upper die 510 and the lower die 520 to avoid affecting subsequent operations.

Specifically, a slider portion 1621 may be provided on the mounting table 162 , a slide rail 166 is mounted on the support frame 165 , and the slider portion 1621 cooperates with the slide rail 166 to guide the sliding of the mounting table 162 .

In this embodiment, the driving part 161 can be a telescopic cylinder or an electric push rod, etc. The movable end of the driving part 161 is connected to the mounting table 162 , and the fixed end of the driving part 161 can be mounted on the mounting seat 134 of the lower mold frame 130 through the mounting frame 167 .

In a specific solution, the combustion medium used by the smoke injection mechanism 160 is acetylene, and the combustion of acetylene in the air is insufficient combustion, so that a carbon deposit layer can be formed in the cavity of the mold 500 . In practice, other gases that can generate carbon deposits can also be used as the combustion medium.

In specific setting, the number of air holes 1632 of the gas ring 163 is consistent with the number of cavities of the mold 500, and when in the ignition position, it corresponds to the position of each cavity, so as to ensure the carbon deposit layer formed on the wall of each cavity.

As shown in FIG. 4 , the gas ring 163 is specifically formed by bending a pipe, one end of which is sealed, and the other port forms an air inlet 1631, which is connected to the gas source with the combustion medium through a pipeline, and can be set on the pipeline On/off valve, the smoke spray mechanism 160 may also be provided with a smoke spray control unit to control the action of the driving component 161 , the opening and closing of the switch valve and the ignition operation of the ignition needle 164 .

Specifically, the smoke spray control unit may communicate with the casting control unit, so as to control the actions of the relevant components of the smoke spray mechanism 160 according to the feedback command of the casting control unit. For example, when the casting control unit feeds back that the upper die 510 and the lower die 520 are in the smoke spraying position, a start signal can be fed back to the smoke spray control unit. After receiving the start signal, the smoke spray control unit sequentially controls the driving component 161 to drive the mounting table 162 Move to the ignition position, open the on-off valve to allow the combustion medium to flow into the gas ring 163, and then ignite the ignition needle 164. After the subsequent smoke spraying is completed, the reverse action of each component is controlled in turn.

It should be noted here that the smoke injection position and the ignition position mentioned here are actually the same position, that is, at this position, the ignition needle 164 can be ignited to cause incomplete combustion of the combustion medium to generate carbon deposits and spray onto the surface of the cavity.

Please refer to FIGS. 6a to 6e. As shown in FIG. 6a, the casting machine 100 is at the clamping position at this time, that is, the clamping cylinder 140 drives the lower mold base 132 to move up to the lower mold 520 and the upper mold base 120 installed thereon.
